result:remove rigid body motion (field)

Version: 0.0.0

Description

Removes rigid body mode from a total displacement field by minimization. Use a reference point in order to subtract its displacement to the result displacement field.

Inputs

This table lists the input pins for this operator. Input pins define the data that the operator requires to perform its operation. Some inputs are required, while others are optional and provide additional configuration. Each parameter is detailed in the sections that follow the table.

field (Pin 0)

• Required: Yes
• Expected type(s): field, fields_container

field or fields container with only one field is expected

reference_node_id (Pin 1)

• Required: No
• Expected type(s): int32

Id of the reference entity (node).

mesh (Pin 7)

• Required: No
• Expected type(s): abstract_meshed_region

default is the mesh in the support

Outputs

This table lists the output pins for this operator. Output pins provide the results of the operator's computation and can be connected to inputs of other operators or retrieved for further processing. Each output is detailed in the sections that follow the table.

field (Pin 0)

• Expected type(s): field

translation_field (Pin 1)

• Expected type(s): field

Global rigid translation vector

rotation_field (Pin 2)

• Expected type(s): field

Global rigid rotation angles

center_field (Pin 3)

• Expected type(s): field

Center of the rigid rotation

Configurations

This operator supports configuration options that modify its behavior.

mutex

• Expected type(s): bool
• Default value: false

If this option is set to true, the shared memory is prevented from being simultaneously accessed by multiple threads.

Scripting

This operator can be accessed through scripting interfaces using these identifiers.

Examples

These examples demonstrate how to use this operator in different programming environments. Each example shows how to instantiate the operator, connect the required inputs, and retrieve the output.
